To detect victimless crimes when there are no formal complaints, police rely on what type of investigative work?

• A. Sting
• B. Patrol
• C. Undercover
• D. Surveillance

Answer: (C)

Victimless crimes often lack a complainant, so investigators must infiltrate the environment where the activity occurs. Undercover work places an officer undercover, sometimes taking part in the activity, to observe and collect evidence over time. This approach reveals ongoing illicit behavior that wouldn’t surface through routine patrols or distant surveillance, and it provides firsthand evidence needed for prosecution. A sting targets a specific planned transaction and isn’t as well-suited for uncovering broader, hidden markets. Patrol focuses on deterrence and quick responses rather than in-depth investigation. Surveillance involves watching without immersion, which can miss the nuances of these hidden activities. So undercover work best enables detection of victimless crimes when there are no formal complaints.
